JOHN W. BAKER, OF PHILADELPHIA, PENNSYLVANIA.

REGENERATIVE GAS-BURNER.

SPECIFICATION forming part of Letters Patent No. 387.844, dated August 14, 1888.

Serial No. 247.715. (No model.)

To all whom it may concern:

Be it known that I, JOHN W. BAKER, a citizen of the United States, residing in the city and county of Philadelphia, State of Pennsylvania,haveinvented anew and useful Improvement in Regenerative Gas-Burners, which improvement is fully set forth in the following specification and accompanying drawings.

My invention relates to improvements in regenerative ges-burners; and it consists in the combination and arrangement of parts, as hereinafter set forth and claimed.

Figure 1 is a vertical section of a weltknown forni of regenerative gas-lamp with my iinprovexnents annexed. Fig. 2 is aplan view of the lamp. Fig. 3 is a detail view showing the air-register. Figs. 4 and 5 are detail views showing the gas-ports.

Similar letters of reference indicate correspending parts in the several figures.

It is not necessary to describe the general construction of the lamp, as it is old and well known, so will simply describe myimprovements and their functions.

Referring to the drawings, A A is a registering-damper having registering-holes D D, adapted to regulate the outow of the products of combustion in the exit-pipe or chimney K. This damper is located in the top of the chimney, and is secured, as shown, by a screw, C, to the gas pipe G.

G is the burner, having gas-conveying tubes E E running from the chamber H, attached to the gas-pipe G', to the base of the lamp. To the lower ends of these tubes is secured an annular' chamber, E', which is provided with a series of peripheral openings, F, and aseries of base-openings, M. These holes F and M are arranged atan angle to each other-preferably a right angle-and so that as the gas is forced out the draft, as shown by the Iarrows, forces the two jets together and makes a single dame.

B B is an adjustable spreader or button attached to the base of the gas-chamber H by a screw, P, and having a perforated spreadercup, Z. By means of the screw P and button B thesize of the openingbetween the said button and inner Walls of the chamber E is adjusted so that the interior draft is regulated, and by means of the spreadercup Z the direction and t amount of flame from the port M is controlled.

The arrows show the direction of the drafts in thelamps, and the'direction of the combined flame is seen at the exit of the ports E M.

The operation of the device is obvious and needs no further explanation.

Having thus described my inventioxrwhatl claim as new, and desire to secure by Letters Patent, is-

l. In a regenerative gas-lamp, a gas-chainber with tubes leading therefrom into an annular chamber, the latter having peripheral and base openings, and an adjustable perforated spreader-cup, said parts being combined substantially as and for the purpose set forth.

2. The gas-chamber lll, the tubes E, leading therefrom, the chamber E', having base-open ings M and peripheral openings F, the spread` er-cup Z, the button B, and the adjusting-screw P, said parts being combined and arranged substantially as and for the purpose set forth.
